Yuri Muzychka - Thermal Simulation Tools

The following tools were developed to assist in the calculation of mean and maximum heat source temperature for single heat source systems and multi heat source systems. The models are Fourier series based solutions for 2 and 3-dimensional conduction. Applications include: LED arrays, GaN HEMT's, Heat Sinks, Heat Spreaders, Curcuit Boards, etc.

  • Circular Disk with Circular Heat Source and Adiabatic Edges

The above tool is based on the models presented in the following paper:

Y.S. Muzychka, "Thermal Spreading Resistances in Compound Orthotropic Circular Disks and Rectangular Channels with Interfacial Resistance", Accepted for publication in the Journal of  Thermophysics and Heat Transfer, 2013.

  • Rectangular Heat Flux Channel with Multiple Eccentric Heat Sources and Adiabatic Edges

The above tool can be used for single or multiple discrete heat sources, single or multiple strip heat sources, or a single central heat source (to represent a basic element from a larger array). The above tool is based on the models presented in the following paper:

Y.S. Muzychka, K. Bagnall, and E. Wang, "Thermal Spreading Resistance and Heat Source Temperature in Compound Orthotropic Systems with Interfacial Resistance", Accepted for publication in the IEEE Transactions on Components and Packaging Technologies, 2013.

  • Rectangular Heat Flux Channel with a Central Heat Heat Source and Edge Conductance

The above tool can be used to model strip or rectangular heat sources on symmetric rectangular slab with edge cooling. The edge conductance hx does not have to equal the edge conductance hy. More information on the model can be found in the following paper:
